Create the Warehouse connection in Hightouch

You'll need to allowlist Hightouch's IP addresses to allow our systems to contact your warehouse. Reference our docs to determine which IPs you need to allowlist.

  1. In Hightouch, go to Sources or click

  2. Click "Add Source"

  3. Select SQL Server, and click "Connect Source"

  4. Enter your hostname (IP address or Azure hostname)

  5. For Port, enter your port. This is 1433 by default.

  6. For Database, enter your database name.

  7. For Username, enter your SQL Server username.

  8. For Password, enter your SQL Server password

  9. Click "Test" to test the connection. Hightouch is able to successfully connect, click the "Complete" button at the bottom of the page

If you see the following error message, you need to update your firewall settings in your Azure Console.

Azure Firewall Setup

By default, Azure will protect your SQL Server from any external IP address from connecting to your SQL Server. Below are the steps to add Hightouch's IP addresses to the firewall.

  1. Log into your Azure Console Dashboard
  2. Click on "SQL databases"
  3. Select the SQL database that you want to update
  4. Click on "Set server firewall"
  5. Allowlist the Hightouch IPs listed above.
  6. Click save button in top upper left corner


If your SQL Server is not "publicly accessible", you have two options

  • SSH tunnel: Hightouch will connect to your SQL Server via an SSH tunnel established from Hightouch's servers to a bastion server in your VPC.
  • Reverse SSH tunnel: You will establish an SSH connection from a bastion server in your VPC to Hightouch's servers, and Hightouch will reuse that connection to connect to SQL Server.

Both of these options are now self-serve and can be referenced here.
